Hi Mark, I ended my last (final) long distance Cycle trip in 2004 with 3 months cycling around southern India. Some words of advice:
1. All other road users are out to kill you.
2. They really are.
3. Be prepared to bail out into the ditch, any ditch, at any time.
4. When you stop cover the bars and all clicky bits with a cloth. Most Indians will not steal but when they see your star ship, compared to their clunkers, they must fiddle. What they cannot see they will not fiddle with. This includes when leaving it under the eagle eye of a security guard who will fight to the death to stop your bike being stolen but cannot stop playing with clicky levers.
5. All other road users are out to kill you.
The place and the people are magic, really magic but ignore 1. 2. 3. and 5 at your peril. Ride safe, enjoy your trip.
